Tile Roof Restorations

If a full roof restoration is out of your budget, tile roof repairs is an option.

JMZ Roof Restoration is able to assist with cleaning and repairing of your tiled roof, however, we’ll always be upfront and advise if we think a full restoration will offer you better protection and be more cost effective in the long run.

If you’re only considering repairs – and not a roof restoration project – we strongly advise clients to look at the bigger picture. A home is usually your biggest financial asset, so if it’s important to you to protect everything you’ve worked hard for a restoration may offer greater peace of mind and security.

The age and condition of your roof may also indicate that more significant repairs are required. Generally, tiled roofs aged between 10 – 15 years old and have not been maintained will require some degree of repair/maintenance due to the porous nature of roof tiles and natural movement of homes in hot and cold conditions.

Regardless of which option you go with, regular roof tile maintenance is a must. You might also be surprised to hear that most Home and Contents Insurance Companies will not cover damages where it it found that general maintenance of a roof has been neglected by the homeowner.

Common Problems found in Tiled Roofs

Deterioration of roof tiles from weathering, ground movement or even walking a roof by an inexperienced person can cause roof tiles to crack, break or be chipped. Leaving tiles in this condition result in water leaks during rainfall.

A combination of age, ground movement and poor pointing materials used in the initial construction of your roof generally leaves ridgecaps opened to potential leak issues.

Cement Pointing a combination of sand and cement that was once a common bonding agent used in roofing, ages and breaks down with ground movement and weathering. Flexible Pointing is now available and has replaced Cement Pointing. Globalcote Flexible pointing is JMZ’s preferred adhesive for the securing of Ridgecaps to a roof surface.

Tile clips help keep roof tiles in place. Tile clips are located and sit on a water course channel underneath a row of roof tiles. Tile Clips are know to commonly break and as they do become clogged causing blockages and a free flow of water from own the water course channel. As a result, water leaks become evident.

Valley Clips secure cut tiles in valleys. It is known that these clips can break causing tiles in the valleys to slip resulting in water leaks.

Description Title

Is a Foil designed to reduce the transmission of moisture into a home and acts as a second skin to protect your interior from storm driven rain and dust. Ageing of this foil can result in tears requiring either replacement or repair. It is also now commonly found that during install of other items to the roof surface like skylights or solar can result in third parties cutting into the sarking film leaving an open area for water to enter into the roof cavity during rainfall.

A gutter system installed during construction of a home where 2 roofs meet. Valley Irons allow water to flow down off a roof and into the gutters. Valley Irons can be found to be installed not wide enough and during heavy rainfall cannot cope with the volume of water and channel it down the roof into the gutters. A solution to this issue can either be widening the valleys or installing Valley seal to block water away from entering inside a roof.

Valley Seal is a foam product that is designed to prevent water entering into a roof cavity during heavy rainfall. Like all products exposed to the elements and weathering valley seal can deteriorate and over a long period of time needs to be replaced.
